The pure elements / gases under pressure in these tubes is generally used to produce a light for spectral analysis. Brightness of the light discharge depends on the power of electrical energy being supplied to the tube. The nature of gas determines the pure spectral color and usually is of a relatively low band width. All lamps contain metal ends with long-life electrodes. Lamps are about 26 cm (10 inches) long, with 90-100 mm of central capillary. (They may be operated continuously when used with the LAKHOVSKY machine, as shown in the instructions for that device.)
Lamps are intended for intermittent use only at full power, and not for use as a lamp source. These are designed to operate 30 seconds ON – 30 seconds OFF.
Requires a Spectrum Tube Power Supply such as our low-cost NEON21 for do-it-yourselfers, or the finished Spectrum Tube Power Supply 2154-1, or our Induction Coil Power Supply 1917-10 to operate (each sold separately).
May also be used to extend the frequency spectrum of Lakhovsky machines and Tesla Coils.
